STRAW-BINDING MACHINE.

Application filed December 21, 1923.

To all whom it may concern:

Be it known that 1, JOHN B. KRAUsE, a citizen of the United States,residing at Hillsboro, in the county of Marion and State of Kansas, haveinvented certain new and useful Improvements in Straw-Binding Machines,of which the following is a specification.

This invention relates to an improvement in straw binders and has moreparticular reference to a machine for use in the binding of bundles ofstraw, the primary object of the invention residing in the provision ofsuch a machine wherein the butt ends of the outside strands of straw areemployed for the binding algent.

An additional object of the present invention resides in the provisionof means for picking out the outside strands of straw and reverselybending the butt ends thereof whereby the same may be so acted upon byother parts of the machine for producing the binding agent.

Yet another object of the invention is to provide a binding machinewherein the same may be operated by unskilled persons and wherein thesame will operate effectively under all conditions, the machine beingfur ther characterized by the fact that a great amount of bundles ofstraw may be bound in the minimum amount of time.

Vith the above andother objects in View as the nature of the inventionwill be better understood, the same comprises the novel form,combination and arrangement of parts hereinafter more fully described,shown in the accompanying drawings and claimed.

In the drawings wherein like reference characters indicate correspondingparts throughout the diiterent views,

the carrying arm for said twisting member being shown in cross section,

Figure 5 is a detailed transverse cross sectional View of said strawtwisting mechanism and taken substantially upon the line 55 of Figure 4,

Figure 6 is a detail vertical cross sectional view of the straw testingmember, taken on the line 66 of Figure 7.

Figure 7 is a front elevational view of the straw twisting member.

Figure 8 is a fragmentary side elevational view of the picking member ofthe present invention.

In carrying out this invention it is my purpose to provide a bindingmechanism to be employed in lieu of the usual costly and complicatedbinding mechanisms now employed in conjunction with havesting ma chines,and in the present instance, 5 desig nates the floor or platform that isformed with a transverse elongated slot 6 through which extends the.compressing mechanism including the usual clamping jaws 7-7 and thatserve as a means for tightly compressing the bundle of straw or wheat asthe case may be, which bundle is designated by the reference characterA. The usual straw or wheat bundle picking arm 7 upon one end of a shaft8 is not of the essence of my invention and will not be claimed by me.

My invention per se embodies the provision of a stubshaft 9 j ournaledthrough an opening in the right angular portion 10 of the usual hollowhorizontally disposed arm 11 through which is guided the beforementioned shaft 8 of the picking arm '7, this right angular portion 10being formed upon or otherwise suitably secured to the plat form 5. Uponthe right hand end of this stubshaft 9 there is keyed sprocket gear 11'over which is trained a sprocket gear 12 that extends downwardly throughthe plat form 5 due to the presence of an opening 18 therein and thentrained over another sprocket gear of the power mechanism, not shown.

Formed around the inner side of the opening in said right angularportion 10 of the hollow arm 11 is a boss 14, rigid with which is arelatively large spur gear 15 and disposed for rotation around which isa suitably formed gear casing 16.

The inner end of said stub shaft 9 extends through the before mentionedboss 14 and is rigidly secured as at 17 to the hollow con necting rod 18by a pair of laterally extending spaced parallel hollow arms 19 and 20,respectively.

Disposed for free rotation within the arms 19 and 20 are horizontalshafts 19 and 20' respectively, the inner ends of which ex tend withinthe gear casing 16 and are equipped with spur gears 19' and 20respectively, that are in mesh with the teeth of the before mentionedrelatively large spur gear 15 rigidly secured to the boss 14 wherebywhen the arms 19 and 20 carrying said shafts are moved around the bundleof straw or grain A, said shafts 19 and 20 will be rotated.

The opposite ends of these horizontal shafts extend beyond the adjacentends of the arms 19 and 20 and detachably secured to the projecting endof the shaft 20 is a finger 21 which seizes and turns outwardly the buttends of the outer layers of straws of the bundle A as said shaft 20 isbeing rotated so that said out-turned ends of the straws will besubsequently received by a twisting device carried by the projecting endof the other shaft 19.

The twisting device constitutes the provision of a sleeve 22 that isformed upon the free end of the shaft carrying arm 19, said sleeve beingformed upon the inner side of the arm and pendant therefrom so as to bein a plane substantially vertical with respect to the longitudinal axisof the arm 19.

The front side of this sleeve 22 is open and formed upon the oppositeedges of said opening are forwardly extending outwardly converging lips23 for forming a month Within which enter the reversely bent stub endsof the strands of the bundle A that have been acted upon by the finger21, this action being clearly shown in Figures 1 and 2.

Journaled through an opening in the upper closed end of said sleeve 22as more clearly shown in Figure 6, is a vertically disposed stub shaft24: that is provided at its upper end with a gear 25 that is in meshwith a gear 26 upon the end of the shaft 19' it being noted that theupper end of said sleeve 22 is so formed as to provide a section of agear casing for said gears for co-operation with a similar formedremovable section 27.

The lower end of this stub shaft 2 1 is equipped with a relativelyZ-shaped cross finger 28 the ends of which lie adjacent the internalwall of the sleeve 24 and which serve as a means for effectivelytwisting the reversely bent butt ends of the straw strands after thesame have passed into the sleeve through the mouth formed by saidconverging lips 2323.

The lower end of the sleeve 22 is formed with a rearwardly extendingdischarge noz- Zle 28 and it will thus be seen that in operation thebutt ends of the outside strands of straw or wheat in the bundle A, willbe acted on by the finger 21 for reversely bending these butt ends intothe position shown in Figures 1 and 2, after which the same Will passinto the sleeve 23 at the point adj acent the bend, after which theywill be engaged by the V-shaped member 28 upon the end of the shaft 24which will thereby cf 9 fectively twist these reversely bent ends of thestrands of straw. A continued movement of the arm 19 around the bundleof straw will manifestly discharge the twisted strands for therebyforming an effective binding for the bundle of straw or wheat.

The specific operation together with numerous advantages of a strawbinding machine of the present character will be at once appreciated bythose skilled in the art, and even though I have herein set forth themost practical embodiment of the invention with which I am at this timefamiliar, it is nevertheless tobe understood that minor changes may bemade in the invention without departing from the spirit and scope of theappended claims. I

Having thus described my invention, what I claim as new and desire tosecure by Let-- ters Patent is 1. In a bundle binding mechanism of theclass described, a bundle compressor, a pair of inter-joined membersmovable around said bundle, means carried by one of said members forreversely bending the stub ends of the outside strands of the bundle,and means carried by the other of said members for inter-twisting saidreversely bent strands and wrapping the same around the bundle,

2. In a bundle binding mechanism of the class described, a pair ofspaced horizontal arms movable around said bundle, means carried by oneof said arms for seizing and reversely bending the stub ends of theoutside strands of the bundle, and means carried by the other of saidarms for intertwisting said reversely bent strands and wrapping the samearound the bundle,

3. In a bundle binding mechanism of the class described, a bundlecompressor, a support at one side of said compressor, a pair ofinterconnected spaced arms mounted upon said support for movement aroundthe bundle held by the compressor, means carried by the foremost arm forseizing and reversely bending the stub ends of the outside strands ofthe bundle, and means carried by the rearmost arm for inter-twistingsaid reversely bent strands and Wrapping the same around the bundle.

4-. In a bundle binding mechanism of the class described, a bundlecompressor, a support at one side of said compressor, a pair ofinter-connected spaced arms mounted upon said support for moving aroundthe bundle held by the compressor, a rotary finger carried by one of thearms for seizing and reversely bending certain of the outside strands ofthe bundle, and means carried by the other arm for receiving, twisting,and discharging said reversely bent strands.

In testimony whereof I aflix my signature.

JOHN B. KRAUSE.
